[PATCH RFC] aquantia-firmware: package MediaTek's Aquantia AQR113C firmware

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

Aquantia AQR113C is PHY that needs loading a firmware. Some devices may
have it stored on flash and some need filesystem to provide it.

MediaTek holds its own AQR113C firmware file for its boards. Package it.

The problem is obtaining that firmware:
1. Cloning whole repo seems like an overkill for copying a single file
2. Public git server doesn't support git protocol (and so git archive)
3. Gitiles UI doesn't allow downloading raw files (nor binaries as text)

The only option seems to be downloading tar archive of "firmware"
directory. The problem is such archives generated by Gitiles differ on
every download so a checksum can't be specified.

Due to all above a custom download is implemented in "Build/Prepare".
Then firmware gets simply extracted and packaged.
